Security Hardening for DLL Files

Ensure that all SO dynamic link library (DLL) files (such as SO files in the LD_LIBRARY_PATH) used during system running are owned by the current user or root user and their permissions meet the security requirements of your organization.

You can run the ls -l {path} command to view the owner information about a specified file or all files in a specified directory. In the command, {path} indicates the directory or file path.
